Yes they do, it is a big Universe out there and in order for a Sentient Alien race to send some representatives to Earth would require the entire race to work together in order to construct such a SpaceShip. It would take a biblical event in order to convince all of them to do this and they would need to be shown exactly where Earth is. It requires technology from Heaven just like HumanKind's technology, but shaped in a way and sequence that the race survives and its representatives succeeds in reaching Earth.
So with Heaven's involvement they might speak English, their computer programming might also be English and their circuitry might also use the same coding as HumanKinds.
So when such Astronauts arrive on Earth HumanKind should be respectful and treat them kindly, it is a marvellous achievement for them to reach here. Consequences of people being hostile or rude would lead to the offender being an embarrassment to all of HumanKind and wind up getting punished later in Purgatory as it would upset everyone.
Later HumanKind will experience a Super Golden Age and be blessed with the ability to use wormholes with Heaven's permission in order to build SpaceShips of our own that are massive and can take the Sentient Alien Astronauts back to their home world. This could lead to trade in goods and technology and tourism.
Would you ever think that there was technology developed on Earth that could be traded with not only Sentient Alien races but also Heaven? :music_whistling:
